We demonstrated the fabrication and characterization of dye-sensitized solar cells by using biomass material. Specifically, we fabricated the biomass base platinum-electrodes. The solar cells had a photovoltaic conversion efficiency (η) of 1.36% under AM 1.5G at 100 × 10-3W m-2. Additionally, the photovoltaic performance at the higher efficiency was obtained by using counter-electrode with a platinum-thickness of～100 × 10-9m. These results indicate that our techniques can be used for future research on the fabrication of biomass materials based eco-devices.
